top 10/most popular lists
What''s the best way to handle views that show the top 10/most popular/
Recently updated/most commented type listing?
Should I have a separate model that is populated with records from
other models by a background job or should I need to use some sort of
caching? Perhaps both?
Thanks!

http caching a dynamic page
Is it possible to take advantage of http caching/proxy caching with
dynamic pages? i.e. pages with section/part that can change over time
but certain part of the page remain the same. I would rather not keep
re-rendering the static part but insure the dynamic part are rendered
with fresh data.
I am using memcached mostly as an object store that I can minimize db
hits but I still am rendering a

Newbie question on has_many
I have two classes: a Widget and a User. The User has an id that is
referenced in two places on the Widget: owner_id and operator_id.
How should I structure that reference for has_many?
Thanks folks - I appreciate any help on this.

Relationships question (?)

The problem we have is the following:
We have a User model (id, username, password, email) and we have a
Document model (id, name, content, owner_id). A

Shared Queue / Exclusive Query Results
My application is going to have a work queue of scheduled tasks stored
in the DB. This work queue will be shared across multiple Rails app
servers. I need a way to ensure that no two servers get the same jobs
if multiple servers pop jobs off the top of the queue simultaneously.
Is there a fairly simple way to acheive this? Or do I need to come up
with some fancy secondary server to dispatch

associations help?
I have Users who can "own" Projects. There is only one owner. Users in

at this:

creating and storing records in Ruby
I''ve read through my RoR books and I can''t seem to find the solution.
This is a pretty basic, easy, and practical application for RoR. If you
guys know of any resources on the net to answer these questions let me
know.

Edge rails, single table inheritance and keeping multiple classes in a single file
So is the official stance as per edge rails that multiple class
definitions must go into separate files? I was trying to use STI with
acts_as_attachment, to have all my attachment classes go into a single
file, for example:
attachment.rb
class Attachment < ActiveRecord::Base

find_in_batches vs limit
Is the :limit option in the regular find call effectively same as
doing find_in_batches? or does doing something like the following
loads "all" of the record and then returns only 5?
find(:all, :conditions => [''age > ?'', age], :limit => 5)
